Definition of Broadband
Many consider the definition tied to the upload/download speeds that can be achieved, while others also may consider the type of connection in question, and still others define broadband by what it is not. Most people agree that neither dial up internet or ISDN internet is of broadband speeds. In mobile internet, similarly, most consider internet over GSM or GPRS to be low-band, not broadband internet. Of the dial up with 56 kbit/s (using the V.90 or V.92 protocol) modem the download speeds top at that rate, while with ISDN typically provides a maximum of 128 kbit/s, neither, as stated, being of broadband speed. The broadband speeds are often considered starting with speeds typical to DSL (Digital Subscriber Line) internet access and cable broadband internet, which are often much more than the fastest slow-band (ISDN). In wireless internet, the technologies that are considered broadband include UMTS/3G, HSPA, and EVDO. Increasingly popular broadband wireless technology is the WiMAX, the Worldwide Interoperability for Microwave Access, which is a telecommunications technology aimed at providing wireless data over long distances in a variety of ways, from point-to-point links to full mobile cellular type access. |
